Do Not Threaten

Ephesians 6:5 Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as unto Christ;
6 Not with eyeservice, as menpleasers; but as the servants of Christ, doing the will of God from the heart;
7 With good will doing service, as to the Lord, and not to men:
8 Knowing that whatsoever good thing any man doeth, the same shall he receive of the Lord, whether he be bond or free.
9 And, ye masters, do the same things unto them, forbearing threatening [NIV: do not threaten them]: knowing that your Master also is in heaven; neither is there respect of persons with him.

1 Peter 2:18 Servants, be subject to your masters with all fear; not only to the good and gentle, but also to the froward.
19 For this is thankworthy, if a man for conscience toward God endure grief, suffering wrongfully.
20 For what glory is it, if, when ye be buffeted for your faults, ye shall take it patiently? but if, when ye do well, and suffer for it, ye take it patiently, this is acceptable with God.
21 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:
22 Who did no sin, neither was guile found in his mouth:
23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously:
24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
